Specifically, referring to fig. 1, the first cushion member 1 includes a fixing portion 11, an ejector 12, and a cushion portion 13. The fixing part 11 is fixedly connected to a chassis of a vehicle; the ejector 12 is connected to the fixed portion 11, and the ejector 12 is displaceable relative to the fixed portion 11; meanwhile, the buffer part 13 is connected to the ejecting device 12, so that the ejecting device 12 can drive the buffer part 13 to displace, and the buffer part 13 is a part with elasticity; when the ejector 12 is not displaced, the buffer portion 13 is located in the vehicle body, that is, the entire first buffer unit 1 is hidden in the vehicle body during daily use.

When the collision prediction module 100 determines that the vehicle meets the collision condition, the pop-up device 12 responds to the collision prediction module 100, displaces relative to the fixing portion 11, and drives the buffer portion 13 to move towards the direction away from the fixing portion 11 until the buffer portion 13 moves to the outside of the vehicle body, at this time, when the vehicle encounters a collision, an object in front of or behind the vehicle collides with the buffer portion 13, and the buffer portion 13 has elasticity, so that the buffer portion 13 can buffer the impact force of the vehicle, the damage of the vehicle is reduced, and the casualties are reduced; after the collision, if the buffer part 13 is not damaged, the pop-up device 12 can drive the buffer part 13 to return to the vehicle body again.
